Broaching instruments divided into multiple parts to reduce the size of incisions necessary to perform a total hip arhroplasty, minimizing trauma to tissue surrounding the hip joint. One approach is to divide the broach head into first and second segments for insertion through posterior and anterior incisions, respectively, and interconnection within the patient. Methods of preparing the proximal medullary canal of a femur for receiving a hip stem implant utilize the multi-part broaching instruments and two-incision techniques to introduce the broaching instruments into the patient for broaching the canal in preparation for receiving the implant.

A prosthesis for replacement of a ball and socket joint in the human body. The prosthetic components comprise a plurality of separate parts which may be inserted through a hole in the femur of the patient and assembled and attached to the prepared acetabulum of the hip bone to form a cup-shaped first shell. A cup is also passed through the hole in the femur and attached to the first shell to form the socket portion of the joint. A shaft having a first end with a ball formed thereon is inserted in the hole through the femur so that the ball engages the cup for movement therein.

The acetabular cup is adapted to be secured within a hip bone. The liner includes a hemispherical inside surface for pivotably supporting a head at an upper end of a femur. The locking ring resides within an annular groove in the acetabular cup and an annular seat in the liner. The locking ring includes a captured end and a free end. The captured end includes a slot which cooperates with a post in the acetabular cup to slidably hold the captured end to the acetabular cup. The locking ring removably attaches the liner to the acetabular cup.

The present disclosure provides a femoral prosthesis for use during a revision procedure. The femoral prosthesis includes a body, a neck, a stem, and a sleeve. The sleeve facilitates reattachment of an osteotomized proximal femur, specifically the greater trochanter, following a revision femoral prosthesis surgery involving an extended trochanteric osteotomy. Additionally, the sleeve promotes ingrowth of the osteotomized proximal femur with the sleeve.

A system and method are provided for helping implant a hip prosthesis in an individual, which includes an acetabulum intended to be placed in the hip bone of the patient and a femoral part intended to be integrally connected to the femur of the individual. The method includes: obtaining, before the operation, images issued by a device that images a human body and locates a position of images in space. The images are taken in at least three reference positions: standing; recumbent; and sitting. Before the operation, the method determines a pelvis version of the individual in different positions by analyzing the images. During the operation, the method measures a position of the acetabulum with relation to the pelvis of the individual, and simultaneously restores information representative of prosthetic mobility of the hip with relation to each of the reference positions, for a current position of the acetabulum.

Exercise machines for the leg muscles using separate machines for the biceps femoris and quadriceps and with the biceps femoris machines configured so that the muscle attachment below the knee is the “origin” and the muscle attachment on the upper leg and hip bone is the “insertion”.

The invention relates a nature hipbone device which includes a cotyle cup, an orientation pivot which localizes the cotyle cup in its place, is fixed on the close end of the cotyle cup; at least one link member which is hinged onto the opening edge of the end of the cotyle cup, at least one lock member which sleeve on the edge of an end of the link member apart from the cotyle cup may be located on secure place by the lock member.

In a human hip replacement process, the steps include providing a selected size generally longitudinally extending stem and laterally angled neck, the stem received endwise into a recess in an elongated femur, there being a ball on the neck, the neck and stem having a non-circular tongue and groove interfit connection to resist relative rotary displacement therebetween, the connection defining a generally longitudinal axis, fitting the ball in a socket on a hip bone, to pivot in the socket, the selection of stem and neck, and tongue and groove connection between the size selected stem and neck, enabling accurate pivoting of the ball. A set of different size balls and neck units are enabled for selective choice, as during surgery.

A safety harness consists of a harness similar at first glance to other harnesses of the type but with the added feature of a conical waistbelt and specially contoured shoulder pads. The conical waistbelt allows for more weight to be distributed straight on top of the hip bones thus reducing the amount of weight the shoulders must bear. By having less weight on the shoulders, back pain is dramatically reduced. The contouring of the shoulder pads also allows for a greater freedom of movement.

The alone old people automatic monitoring system comprises an old people living environment monitoring module, a falling-down monitoring module, a heart rate monitoring module, an alarming module and a community module; all-directional living monitoring is carried out on old people by utilizing a temperature sensor, a humidity sensor, a flame sensor, a photosensitive sensor and a smoke module; a three-axis angle sensor and a three-axis accelerated speed sensor, and a gyroscope are combined to judge a falling-down condition of the old people; the heart rate of the old people is detected by a pulse sensor; monitored falling-down and heart rate conditions are stably combined to judge whether the old people are at a dangerous state or not; other people are announced to help to alarming and do first aid through a voice alarming function in the alarming module, and a recording function can obtain scene evidences; a GPRS (General Packet Radio Service) short message reports current positioning information of patients to guardians; a wearing position of wearing equipment is close to a hip bone, the monitoring errors are reduced and the monitoring accuracy is improved.

A method for avoiding impingement between an implanted prosthetic hip stem and acetabular cup uses at least one digital x-ray of a standing patient preferably including a lateral x-ray to determine a pelvic tilt angle of the patient. A hip stem is virtually implanted at an initial stem version angle into a virtual femur constructed from the digital x-ray. Data of at least one hip joint motion is obtained from at least one individual. A range of inclination and anteversion angles is calculated for a virtually implanted acetabular cup that avoids impingement with the virtually implanted hip stem. The calculated range of inclination or anteversion angles is based at least in part on the pelvic tilt angle of the patient, the initial hip stem version angle and the obtained joint motion data.

The drive unit retracts the right and left hip belts after the engagement detection unit detects an engagement and the detection unit detects that the right hip belt and left hip belt are not making contact with the passenger.

A multiaxial combined and matched type anti-infection semi-pelvic false body comprises an acetabulum and net cup plate wing which is arranged on the top of the acetabulum and can be fixed on a reserved hip bone wing. Two to three universal joints are arranged on the back of the net cup plate wing. The universal joints are opened with a card slot which can be connected with a universal bar. The invention can arbitrarily adjust the height and the point of view of the acetabulum through the combination of the universal joints and the acetabulum to realize the truly anatomical location reconstruction of the hip joint which is not affected by the resection range. The reconstruction of the connection of the pelvic ring and the acetabulum takes the way of universal multi-axis in order to conveniently adjust the location of the acetabulum, thereby assuring the coherence of the limb length after being reconstructed. The location of the acetabulum can be adjusted according to the removal situation of the soft tissue in the operation. Through the sacrum and the contact point of the universal screw of the ischiopubic multi-axis point driven into the pelvic ring, especially multi-nail fixation driven into the lumbar, the hardening stress can be scattered, the hardening stress concentration can be reduced to reduce the complicating disease such as looseness and broken nails.
